In Final Fantasy VII, Cloud is a mercenary and self-proclaimed ex-member of SOLDIER, an elite, genetically augmented military unit operating under the de facto world government, the megacorporation Shinra Electric Power Company. Fighting against Shinra in the resistance group AVALANCHE, and driven by a feud with the primary antagonist, Sephiroth, Cloud learns to accept his troubled past and adapts to his role as a leader. Cloud has also appeared in several other titles outside the Final Fantasy VII continuity, such as Itadaki Street Special, Final Fantasy Tactics, Dissidia Final Fantasy, Super Smash Bros. for Nintendo 3DS and Wii U, Ehrgeiz and the Kingdom Hearts series.
